TRANSMITTER R REPRODUCER.

Specification of Letters Patent.

Patented June 22, 1215.,

Application filed October 28, 1912. Serial No. 728,192.

To all whom it may concern Be it known that I, WILLIAM E. Pnrnon, a citizen of the United States,residing at San Francisco, in the county ofSan Fran-- cisco and State of California, have invented v certain new and useful Improvements in use of the Morse or other code, has for its object a very sensitive instrument which Will readily engage thecharacters produced on a strip of paper by a Morse key or other equivalent means and transmit or reproduce them..

The invention consists in certain improvements in construction, whichwill be fully disclosed in the following specification and claims.

In the, accompanying drawings, which form part of this specification :Figure 1 represents a top plan View of an instrument embodying my invention. Fig. 2 is a side elevation, and Fig. 3 a vertical transverse section on line 3%, Fig. 2.

Reference being had to the drawings and the designating characters thereon, the numeral lindicates a base-plate of usual construction provided with binding-posts 2, 3. The instrument comprises a plate 4: resting on posts 5, and on said plate 4 is a tape carrier 6, formed by a channel or passage 6 of a width corresponding with the Width of the tape 7, which is indented or embossed with characters 8 well known in the Morse or other code systems. In the bottom 9 of the channel 6 is a groove 10 over which the tape travels, propelled in the usual manner by being unwound from one spool or reel and wound upon another.

11, 11 indicate posts,'each provided'with a transverse and adjustable pin 12, 12, on which a shaft 13 is supported, and secured to said shaft is a bar or lever 14, on which a vertically adjustable stylus 15 is supported. To the opposite end of the lever 14 a lever 16, is pivotally secured parallel therewith by a pin 17 and in the rear end ofsaid.

lever 16, is an elongated slot 18 engaged by a stud 19, supported in a post 20.

The lever 16 is extensible, the part 21 being telescopically connected therewith as shown, and on the free end of said lever is a resilient member 22, preferably formed of a piece of light spring steel, and on the bottom ofsaid lever is a contact 23. The member 22 may be secured in a slot 2 1 in the end of the lever 16, by a pin 25, so that it can be moved laterally at its free end.

26 indicates a post on which is a bracket or lateral extension 27 provided with a contact 28, which is engaged by the contact 23 on the lever 16, and in the upper end of said post is a vertically adjustable stud 29 supporting a. contact 30 which is engaged by the member 22.

31 is a post in whose upper end is a verticallv adjustable screw 32 on which is a member 33 of hard rubber or other suitable non-conductor of electricity which regulates the upward movement of the outer end of the member 22.

The resiliency of the member 22 causes it to augment the impact of the contacts 23 and 28 and 22 and 30 and makes the instrument exceedingly quick in its action in opening and closing an electric circuit in series with a sounder or other electrical instrument.

31 is a post supporting a horizontal finger or rod 85 to guide and turn the tape 7 down, as it travels toward the stylus.

The posts 26, 31 and 3-1, are supported on a plate 36 insulated from plate 4 at 1 and arelongitudinally adjustable therein to accommodate extensibility of the lever 16, by means of a screw 37 which is supported in a lug 38 and engages the body or member 39 to which said postsare directly secured in any approved manner. The member 39 is provided with an extension 40 which enters and travels in a groove 11 in the plate 36. The tape 7 is guided at the opposite end of the instrument by an arm 42 on the post 20. The elongated slot 18 in the lever 16, enables the lever with its extensible arm 21 to be raised readily for inserting the tape in the channel 6.

As constructed the levers 14: and 16, form a compound or duplex lever of great sensitiveness and effectiveness in the operation of the instrument.

Itwill be observed that contact at the end of the lever may be made only on 30, or on 23, 28, by properly-ad usting the former contact, or the contacts of the two may be combined by the adjustment of the screw stud 29 to accommodate conditions of tape. This adjustment makes the electrical contact solid and allows for variations in the thickness of paper or the depth of the indentations.

After the contacts are adjusted as required,

the adjustment of stylus l5 raises or lowers the levers and makes the electrical contacts lighter or heavier as desired.

The instrument is properly wired for service, the connectionsbeing underneath the base-plate 1, and are not shown on the drawings.

I for reproducing messages from an embossed The electric circuit is a simple make and break, controlled by the stylus 15 which is vertically adjustable and engages the indentations or embossed dots and dashes on the tape 7 and closes the circuit through the frame 4, levers 14-, 16,23 and 28, and spring 22 and post 30. Post 26 with its bracket 28 and adjustable screw 29, insulated from plate 4 is the other terminal of circuit.

The instrument as constructed is designed tape on local or long distance wires or circuits which can be sent at great speed and reproduced on embossed or printed tape at the distant end ofthe wire or circuit, or it ingly sensitive in its action in transmitting.

the contact by the stylus in faint indentations in the tape traveling under it, which renders the use of tape of varying quality practical. It is found in'practical use that a great variety of paper is supplied, and that in some grades, the indentations are so faint that an ordinary transmitter will nottransmit correctly, but skips or jumps over the paper without engaging with the indentations.

Having thus fully described my invention,

what I claim is 1. An instrument of the class described,

comprising a lever provided with an adjustable stylus, a second lever, a resilient member on the end of said second lever, a contact on the lower side of the second lever,

Copies of this patent may be obtained for five cents each, by addressing thedommissi onerof Patents,

3. Aninstrument of the class described,

comprising .an eXtensiblelever, a stylus carried by one section of said lever, an embossed tape engaged by said stylus, a resilient membercarried on one end and a contact on thelower s ide of said lever, a contact adjacent the aforesaid contact, and an adjustable member supportinga contact engaged by, the freeend ofsaid resilient member. j

4. An instrument" oflthe class described,

comprising a duplex lever, one of whichmembers is pivotally supported at one. end and the opposite end pivotallytconnected to the other member, the latter member being pivotally supported: at one end, and means at the opposite end of said member for making and breaking circuit, and a stylus on onev of said members. p p

5. An instrument of the class described comprising a leverprovided with an elongated slot at one end and pivotally supported therein, means at the opposite end for making and breaking circuit, and an adjustable stylus connected to said lever and adapted to engage an embossed tape.

6. An instrument of the class described, comprising a base-plate, a duplexlever, one member of which-lever being pivotally supported at one endand-the opposite end pivotally connectedto the other member of the lever, the latter member beingpivotally supported at oneend, ,a resilient member carried at one end of the last-mentioned inem ber of said lever and a contact on the lower side thereof, a contactv supportedf-rom the base and arranged adjacent said contact on said lever-member, a stylus carriedby the first member of, said lever, an embossed tape engaged by the stylus,.and a tape guide supported from said base and arranged below said lever to direct saidtape in the path. of the stylus.
